World Series of Fighting’s first-ever lightweight title fight takes place Jan. 18, as undefeated contender Justin Gaethje (10-0) meets Gesias Cavalcante (18-7-1) in a rematch of their original March matchup.

WSOF officials today announced the plans. Tickets for the event go on sale Friday, and the evening’s main card airs live on NBC Sports Network.

Gaethje is an undefeated prospect who fights out of Colorado’s Grudge Training Center. Since making his professional debut in August 2011, Gaethje has rattled off 10 straight wins, including nine by way of stoppage. Gaethje has already competed three times for WSOF, earning wins over Dan Lauzon, Brian Cobb and Cavalcante, who he downed via doctor’s stoppage when a cut ended their first meeting in less than three minutes.

Meanwhile, “JZ” Cavalcante also boasts three WSOF fights, including wins over Tyson Griffin and T.J. O’Brien sandwiched around the disappointing loss to Gaethje. With more than nine years of professional experience, Cavalcante has also fought under the Strikeforce, DREAM and K-1 HERO’s banners.

Johnson and Kyle have been scheduled to meet twice before, with injuries forcing “Rumble” out of a planned September meeting and “MAK” out of a headlining slot at this weekend’s WSOF 7 event.

Bantamweight “Bam Bam” Bollinger makes his WSOF debut. A cast member on this past season of “The Ultimate Fighter 18,” Bollinger scored a TKO win over Rafael de Freitas to earn his way into the house but then failed to make weight for a quarterfinal bout against Anthony Gutierrez and was cut from the show.

Nam looks to rebound from a disappointing March fight with Marlon Moraes. The result came when Nam’s stock was at an all-time high after knocking out Bellator MMA bantamweight champ Eduardo Dantas.

Matt Brown performed an honest career calculation that led him to his decision to retire after his next fight. His opponent, Diego Sanchez, seems to have chosen the opposite path. For many aging fighters, these are the two choices, and neither is an easy one to make.
